Title: Dome for airframe
Inventor: SUZUKI KEIZO
IPC: F41G7/22
Filed: 1989-11-24
Abstract: PURPOSE:To provide an airframe dome improving its infrared transmittance and providing less resistance of air by a method wherein a dome shape is made asymmetrical in such a way as angle between an optical axis of a light wave sensor and an induction plate forming the dome is approximately vertical. CONSTITUTION:An asymmetrical dome (1) acting as a light wave transmissive window has an inductance member (for example MgF2) showing a superior transmissive characteristic in respect to infrared rays and an infrared sensor (2) comprises an infrared detector and an optical system. Infrared ray radiated from a target incident to an induction plate constituting the dome (1) reaches the infrared sensor (2) while a reflection at the surface of the induction member is being restricted low due to the fact that an angle formed by it and the induction plate is approximately a right angle. The dielectric plate through which the infrared rays passes and the dome (3) which is a dielectric plate opposite to the former dielectric plate does not need to transmit the infrared rays, so that it is possible to make an acute angled dome in a manner that its air resistance is reduced. That is, it becomes the same shape as that of a cone member in which a ratio between a dome length L and a dome diameter D is equally increased and as a whole an air resistance of the high-speed airframe is reduced in an entire dome.
